O.K. I get it, Supernova made a really great tail light that must be worth the crazy price of $56. But they also make the same tail light with an adapter for your seat post that costs twice as much - $132. I get that the light is probably really great and worthy of such a steep price, but can anyone explain to me how an adapter is worth $76 - that's more than the light !?! (See http://www.peterwhitecycles.com/supernova.asp ) What am I missing???
More importantly, I suppose, can anyone recommend an adapter that will allow me to mount the cheaper (regular) light to my seatpost?
